Fastening tool acting via an intermediate anvil

摘要

The apparatus comprises a barrel (51), a piston (6) sliding in the barrel, for driving a buffer (3) housed in a fastener guide (7). Between the barrel (51) and the fastener guide (7) are arranged a rigid ring (22) and an elastic ring (24). Inside the elastic ring (24) is disposed a rigid ring (27) of the ring the stroke limiter (22). The head (14) of the piston is tapered and is engageable with a bore (23) of corresponding shape in the rigid ring (22). The rings serve as damper for the piston (6) whose stroke is thus controlled.; The device is mainly used for buildings deburring.
